Chemical bolts yog ib qho uas nquag siv fastener, thiab lawv cov specifications feem ntau yog txiav txim los ntawm txoj kab uas hla, khoom thiab ntev. Lawv yog ib qho ntawm cov cim tseem ceeb rau kev xaiv cov bolts tsim nyog. Kab lus no yuav piav qhia thiab nthuav dav ntawm peb yam no.
1. Tshuaj bolt txoj kab uas hla
Txoj kab uas hla yog ib qho ntawm cov kev qhia tshwj xeeb tshaj plaws ntawm cov tshuaj bolts thiab qhov yooj yim tshaj plaws kom paub qhov txawv. Feem ntau qhia nyob rau hauv nti lossis millimeters, xws li 1/4 nti, 3/8 nti, 1/2 nti, thiab lwm yam. Bolts nrog txawv diameters muaj qhov sib txawv load-bearing capacities. Feem ntau hais lus, qhov loj ntawm txoj kab uas hla, lub zog load-bearing muaj peev xwm ntawm lub ntsia liaj qhov rooj.
2. Cov khoom siv tshuaj lom neeg
Chemical bolts yog ua los ntawm ntau yam ntaub ntawv, xws li carbon steel, stainless hlau, thiab hlau alloy. Kev xaiv cov khoom tshwj xeeb nyob ntawm daim ntawv thov ib puag ncig thiab cov kev xav tau. Cov pa roj carbon steel feem ntau yog siv rau hauv kev siv dav dav thiab tsis tshua muaj kev thauj khoom, thiab tuaj yeem xaiv los ntawm cov pa roj carbon zoo tib yam lossis cov qib siab carbon steel. Stainless hlau feem ntau haum rau cov xwm txheej uas nws raug dej noo ntev los yog qhov yuav tsum tau muaj kev tiv thaiv corrosion. Alloy steel yog ntxiv nrog lwm cov ntsiab lus ntawm cov pa roj carbon steel. Nws muaj lub zog siab thiab kub siab ua haujlwm siab, thiab tsim nyog rau cov xwm txheej uas yuav tsum tau muaj zog bolt.
3. Chemical ntsia liaj qhov rooj ntev
Chemical bolt lengths feem ntau yog qhia hauv inches. Cov lus qhia ntev ntev xws li 1 nti, 2 ntiv tes, 3 ntiv tes, thiab lwm yam. Feem ntau hais lus, qhov ntev ntawm lub ntsia liaj qhov rooj ntev dua li qhov yuav tsum tau ua kom tuab kom ruaj khov. Tsis tas li ntawd, ntau hom kev sib txuas yuav tsum tau bolts ntawm qhov ntev sib txawv rau fastening, thiab qhov ntev tsim nyog yuav tsum tau xaiv raws li qhov xav tau tiag tiag.
Nyob rau hauv luv luv, cov specifications ntawm tshuaj bolts yog lub hauv paus rau kev xaiv thiab siv fasteners. Cov kev qhia tshwj xeeb sib txawv yog tsim rau cov ntawv thov sib txawv thiab cov kev xav tau, thiab tuaj yeem sib txawv hauv ntau lub teb chaws thiab kev lag luam. Yog li ntawd, nws raug pom zoo tias thaum xaiv cov tshuaj bolts, cov kev siv tshwj xeeb yuav tsum tau txiav txim siab thiab cov kws tshaj lij lossis cov kws tshaj lij yuav tsum tau sab laj kom tau txais cov ntaub ntawv qhia tseeb.
